FlexAppeal molecular dynamics, prepared and analysed

Which parts of the molecule move. Peaks are usually loops and termini.

Per-residue assignment at every frame. Vertical stripes are transient melting; horizontal bands are stable elements.

How often each residue pair is in contact across the whole trajectory.

Each measure on its own axis. Energies, temperature and density differ by orders of magnitude, so sharing a plot between any two of them would make their alignment arbitrary and any apparent correlation fictional.

The whole protein as one number, against the experimental active and inactive structures of this same protein: +1 is the active references, -1 the inactive ones. The thin line is per frame and the bold one is smoothed over 2.0 ns. The shaded bands start at s = ±0.2, which is where a label is decided; inside them the protein reads as intermediate.

Each structural motif scored separately, in the colours section 6.1 fixes for them. The whole-protein score above is these weighted by residue count, which is why a small motif moving a long way can leave it almost unchanged. Motifs of unequal discriminating power carry equal residue weight, so read this panel rather than the headline number.

The last frame, motif by motif, with the distances the score is computed from and the nearest reference structure in each ensemble.

At 49.9 ns, the last frame analysed. A label is decided beyond s = ±0.2; inside that the motif reads as intermediate, which is a measurement and not a missing answer. The two half means say whether a motif was still moving: one number at the end cannot distinguish a motif that settled from one that was on its way somewhere. The last column is left blank where too few residues distinguish the reference sets to read a state from their secondary structure.

The measurements every state call on this page is made from, at the first frame and the last. Each residue was resolved at run time from a KLIFS pocket position or a GPCRdb generic number, so the labels name the actual residues rather than a motif in the abstract. This is where a reader checks that the score agrees with the geometry.

Every residue here was resolved at run time from KLIFS pocket positions or GPCRdb generic numbers, which is why the labels name actual residues. A measurement with no reading at either end is left out rather than shown empty.

Secondary structure per residue per frame, with each motif marked down the left edge and the reference ensembles' own consensus in the two columns on the right. A motif whose secondary structure matches the inactive references and not the active ones is the clearest evidence this analysis produces, and it is visible along a row.

The reference structures on the plane their published criterion is drawn on, coloured by what the catalogue calls them, with this run's path across it in dark grey. This is the panel where a threshold that does not separate the clusters is obvious rather than argued about.

The ensemble this run was scored against, and whether our spatial label agrees with the annotation each structure came with. Counted, that agreement is the positive control for the whole method: if the labels did not reproduce the catalogue on structures whose state is known, nothing this page says about a trajectory would mean anything.

20 structures, resolved at run time from the catalogue rather than listed in the code. P1 and P2: our spatial DFG and alphaC labels agree with KLIFS on 17 of 17 structures that carry one. Both labels are measurements here and annotations there. A structure reads "not used" when it has no usable state label or the alignment dropped it; the core panel says how many that was.
